ICE-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 766,111, dated July 26, 1904.

Application filed October 1, 1903. Serial No. 175,320. (No model.)

To all whom it may concern:

Be it known that 1, ROBERT MowERY, a citizen of the United States, and a resident of Hot Springs, in the county of Garland and State of Arkansas, have invented a new and Improved Ice-Cutting Machine, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved cuttingmachine more especially designed for cutting blocks of ice into small pieces for use in hotels and other establishments and arranged to allow convenient and quick handlingof the block during the cutting operation.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of the improvement. Fig. 2 is a sectional side elevation of the sameon the line 2 2 of Fig. 3. Fig. 3 is a plan view of the same, parts being broken out. Fig. 4 is an enlarged transverse section of the improvement on the line i 4 of Fig. 2, and Fig. 5 is a perspective view of a block of ice showing the several cuts.

The cutting-machine is mounted on a suitably-constructed frame A, supporting a feedtable B, over which a block O of ice is moved to successively engage cutting devices D, E, and F, serving to provide the lower portion of the block throughout the length and width thereof with vertically-disposed intersecting cuts C and O and a horizontal cut O approximately at the upper ends of the vertical cuts O and C to form small pieces C", preferably in the form of cubes. (See Fig. 4..)

As shown in the drawings, the cutting devices D and E are in the form of gangs of circular saws, while the cutting device F is in the shape of a horizontally-disposed endless band or link saw. The circular saws of the cutting devices D and E are disposed verti-' cally and project through slots in the feedtable B a distance corresponding to the height 5 and width of a piece O, and the upper or cutting run of the band-saw extends about the same distance above the feed-table, while the lower run of the said band-saw is a distance below the feed-table, and between the upper and lower runs of the band-saw extends a chute G for carrying the pieces (1* to a box or other receptacle. (See Figs. 1 and 4:.)

The circular saws of the cutting device D are secured on an arbor H. extending longitudinally below the feed-table and journaled in suitable bearings attached to the frame A. On the outer end of the arbor H are arranged fast and loose pulleys 1, connected by belt with other machinery for imparting a rotary 5 motion to the shaft H and the circular saws of the cutting device 1), secured thereon. The inner end of the arbor H is connected by a bevel gear-wheel J with a bevel gear-wheel J, fastened on an arbor K, carrying the cir- 7 cular saws of the cutting device E, the said arbor K extending transversely below the feed-table B. The arbor K is journaled in suitable bearings carried by the frame A, and on the inner or rear end of the said arbor is secured a gear-wheel L, in mesh with a gear-wheel L, fastened on a shaft N, carrying a pulley N, over which passes one end of the band-saw forming the cutting device F, the other end of the said band-saw passing over a similar pulley N fastened on a shaft N, provided with a sprocket-wheel N", connected by a sprocket-chain N with a sprocket-wheel N on the shaft N, so that when the latter is rotated a turning motion is 5 given to the pulleys 1 and N to cause the band-saw to travel in the direction of the arrow a.

By the arrangement described the three cutting devices D, E, and F are driven in unison, 9 and by reference to Fig. 3 it will be seen that the circular saws of the cutting device D stand at right angles to the circular saws of the cutting device E and the endless band-saw of the cutting device F extends longitudinally, so that a block O can be readily moved over the feed -table to successively engage the said cutting devices to provide the same at the under side with the cuts C, C and C above mentioned.

It is understood that the teeth of the bandsaw F are at the front edge thereof, as plainly shown in Fig. 3, so that when the block is pushed transversely over the feed-table B after the block has received the cuts C and C then the upper run of the said band-saw cuts the blocli horizontally to form the pieces G and separate the same from the block, the latter sliding over the top of the upper run onto a table B on a level with the upper run of the band-saw and having its left side formed with a downwardly-curved extension B leading to the starting-point of the feed-table B in the rear of the cutting dev'ice'D.

In order to insure a proper running of the endless band-saw, the shaft N above men tioned, is journaled in bearings 0, held. longitudinally adjustable by screw-rods P, turning in the main frame A, so as to hold the bandsaw stretched to insure proper cutting.

The operation is as follows: When the arbor H is driven, the cutting devices D, E, and F are simultaneously set in motion, and the block of ice C, placed at thestarting-point of the feed-table, is now pushed transversely in the direction of the arrow 6 to bring the block in engagement with the circular saws of the cutting device D for the latter to provide the lower portion of the block with the transverse cuts C. When this has been done, the block is moved longitudinally from the left to the right in the direction of the arrow 0 to bring the block in engagement with the circular saws of the cutting device E, so that the said circular saws provide the lower portion with the longitudinal cuts intersecting the cuts C at right angles, but being preferably of the same depth. The block having the intersecting cuts C and C now stands in front of the band-saw of the cutting device F, and the block is now pushed transversely in the direction of the arrow d for the teeth of the upper run of the band-saw to provide the block with the cut C at the upper ends of the cuts 0 and (J to form the pieces C, as previously mentioned. The pieces C as cut off drop into the upper end of the chute G, which delivers the pieces to a box or other receptacle.

The block traveling transversely over the top of the upper run of the band-saw finally moves onto the table B, from which the block is pushed longitudinally, but from the right to the left, down over the extension B to again reach the starting-point of the feed-table B in the rear of the cutting device D.

The above-described operation is now repeated to again out pieces C from the lower portion of the block, and the operation is repeated until the entire block is cut into pieces, as described.

From the foregoing it will be seen that the cutting devices are so grouped relative one to the other that the block is moved around in a cycle for cutting the block by successive operations into small pieces or cubes,

Having thus described my invention,I claim as new and desire to secure by Letters Patent 1.
